How to Make a Downspout Diverter

What You'll Need
Lengths of plastic piping, to fit your current pipes
Pipe joints
Cutting tool

If you are concerned about green living, and wish to preserve some of your rainwater for use in the home, or even if you are just having a problem with your guttering, then the downspout diverter is the ideal product for you. This little device can help to distribute some of the water into a rain barrel, onto plants which need watering, or many other locations. Downspout diverters which are sold on the internet can be quite expensive, so if you are keen to make your own and avoid the costs of purchasing one, then follow these simple steps to get the job done.

Step 1 - Cut Your Pipes

Lay out 2 pieces of pipe. These should be of roughly the same length, and measure the same as the piece of piping you intend to replace. Cut out a semi-circle from each pipe, and then bind together using the welder. You should now have a piece of pipe which looks like an inverted "V" shape. Take more layers of pipe, and form a layer of pipe so that the hole at the top will fit your old pipe. You can glue these pieces in place while you work, but be sure to weld them into a solid block before installing.

Step 2 - Add Lengths

The pipes at the bottom will now need to have additional lengths added to them, so that they carry the water away as you decide. One of your pipes should be long enough to lead into the drain, while the other can be attached to a rain barrel, and will only need to be long enough to fit the height of that opening. Fix these openings into place with pipe joints.

Step 3 - Installing

Go to the piece of pipe where you want your downspout diverter to be fitted. Cut away enough of the pipe so that the diverter will fit in, but can still be connected to the top without forming a gap. Slot your diverter into place, and then seal using your welding tool, or just add a joint over the top, which will screw into the wall and help support your diverter. Add a few joints which screw into the wall along the length of your pipe, so that your diverter is fully supported, and then fit the rain barrel.

Step 4 - Testing

Before you decide that your project is finished, it is a good idea to test the diverter to make sure that water reaches the desired location correctly. Put some water into your gutter close to the diverter, and make note of where the water ends up. If should be about 50/50 between drain and rain barrel. If you find that it all falls down the drain, then you should try and move the diverter so that the balance is more towards the barrel. Once you have a good distribution of water, then you can leave your downspout diverter to do its job.
